Daughter of Kōga's leader, Kandō Ueno, and Iga's former leader Tanba Momochi's younger sister Kagari. A symbol of peace between the two factions, she has been brought up carefully and has lived a sheltered life. Because of that, she is an innocent, unfamiliar with the ways of the world. She aspires to contribute to her clan and her people, training diligently.
- Abusive Parents: Kando does nothing but put Enju down, ignore her or use her for the entirety of the game. No matter the route, he coldly cuts Enju off from the rest of the clan after her arrest and sometimes sends her friends to murder herdespite that there's an entire village of other shinobi just as able to do the job. Worst of all, he's doing so either as part of a sick game to choose Hidyori's guardian, or while knowing she's been framed for the murder he ordered.
- Be Careful What You Wish For: Wishes to go on her first mission so that she can be useful to her village and clan, the Koga. Unfortunately, after she completes her mission she's accused of murdering Hideyoshi Toyotomi and is labeled a nukekin.
- Childhood Friends: With Gekkamaru, Kuroyuki, Chōjirō , Kyara and Ennosuke.
- Childhood Friend Romance: In Gekkamuru, Kuroyuki, and Chōjirō's routes.
- Commonality Connection: With Hanzo through her mother.
- Death Seeker: A variation in Goemon's bad ending. Yodo attacks Enju and kills her; Enju admits that she could have dodged it if she had tried, but didn't because she had already accepted that she was going to die either way. Tragically, in this ending she never learns that Goemon had a plan that would have gotten her out alive.
- Hello, [Insert Name Here]: You can rename her, but her default name is Enju.
- Dying Dream: In Kuroyuki's bad ending, Enju is murdered by her father. As she bleeds out, Kuroyuki makes her see an illusion that they're back with all their friends in Koga and everything is safe, ensuring that she dies at peace.
- Dual Wielding: She wields two slender daggers.
- Heroic Self-Deprecation: She is rather hard on herself, particularly when it comes to her skills as a shinobi.
- Interrupted Suicide: Upon learning that Kōga will be destroyed if her head isn't taken to Fushimi Castle in Chōjirō's route, Enju rushes to Gekkamaru, Ennosuke, and Kyara's shared grave and attempts suicide. Chōjirō stops her.
- She also attempts this in Gekkamaru's route after Ennosuke's death. Fortunately, Hanzo stops her just in time and talks her out of it.
- Killing in Self-Defense: In Hanzo's route, Enju is forced to kill one of the Nokizaru shinobi attacking her and Hanzo. Later in the same route, she kills her father in self-defense; notably, these are the only instances throughout any route in which she takes a life.
- Morality Chain: For Kuroyuki in his route.
- Protectorate: Enju is this for Gekkamaru, and effectively for all of Koga as well, since she's basically seen as their princess.
- It's deconstructed in Hanzo's route when Enju realizes that she's completely unprepared for the real life-or-death situation she's now in because she's spent her whole life being protected by others, and resolves to become strong enough to keep herself alive.
- Self-Made Orphan: In Hanzo's route, Enju kills her father in self-defense.
- Shy Blue-Haired Girl: She's generally sweet and somewhat shy, with blue-tinged hair.
- Sheltered Aristocrat: Enju is basically considered the village's princess and thus has never been allowed to go on a mission before; as a result, she is a bit naive about the ways of the world, though it doesn't generally hinder her too much.
- Signature Move: Hyakka Shofuren. She whips up a whirlwind of cherry blossoms around her to hide her from view. She uses it to defeat Goemon in every route, and it becomes prominent in some other routes, particularly Chojiro's, since he's the one who taught it to her.
- These Hands Have Killed: In Hanzo's route, Enju kills one of the Nokizaru shinobi in self-defense and feels extreme guilt over it; she even feels bad about all the ninja that Hanzo has killed defending her, because they were after her in the first place. By the time she takes her father's life at the end of the route, she has come to terms with it, but notably, the good ending concludes with her and Hanzo both giving up the path of the shinobi.
- True Blue Femininity: Both her casual kimono and her shinobi gear is blue.
- "Well Done, Daughter!" Gal: Part of the reason she's so eager to go on a mission is to impress her father, with whom her relationship with is so distant it's practically non-existent.
- You Gotta Have Blue Hair: Enju has light blue hair.
After losing his family, Gekkamaru was adopted by the protagonist's family along with his younger brother when he was three. Assigned to be the Enju's bodyguard, Gekkamaru has proven time and again to be loyal and steadfast. He is known to be one of the most skilled and reliable ninja Kōga has. Gekkamaru is completely devoted to his master and can sometimes be overprotective.
- Adorkable: He's extremely eager to please Enju, often stumbling over himself to accommodate her wishes.
- Big Brother Instinct: He often takes it upon himself to reel in Kuroyuki's antics.
- Bodyguard Crush: To Enju. He's been protecting her ever since she was little and he's grown overprotective to the point that everyone can see it. It may be because of the jutsu Kagari placed upon him when he was small that he's so obsessed with protecting her.
- Break His Heart to Save Him: One of the options to break Kagari's jutsu to have Gekkamaru stop protecting Enju is to show him that she's in love with someone else. Given this, it's probable that the jutsu is broken in the other routes where she falls in love with someone else.
- Dogged Nice Guy: In all routes except his own, of the Low-Key Yearning variety. He is so devoted to Enju that he would think nothing of abandoning his village, or his own life, to keep her safe. In every single route, he abandons Koga without hesitation in order to break Enju out of prison, although someone may beat him to it depending on the route. In Chojiro's route, he even dies to protect her. It's justified, as he is working under the spell Enju's mother had cast on him as a child to protect Enju at all cost.
- Everyone Can See It: Gekkamaru's devotion to protecting Enju runs deep, but Enju remains oblivious to why he's so protective of her besides the fact that "it's his duty."
- Glowing Eyes of Doom: Whenever Gekkamaru's eyes glow, it means Kagari's protection spell is influencing him and anyone posing a threat to Enju better run.
- "I Know You Are in There Somewhere" Fight: After Enju breaks Kagari's protection spell and reactivates his mother's spell that causes him to attack her, she tries to appeal to him in this way.
- Mutual Kill: With Ennosuke on Chojiro's route.
- Not Blood Siblings: Gekkamaru was adopted into the Koga family and was raised with Enju as an older brother and bodyguard.
- Only Mostly Dead: The end of his route. He stabs himself in an effort to stop his body from fulfilling his mother's spell, and Enju is left thinking he was dead for a while. He shows up again for the finale, supposedly having been saved by the Tokugowa shinobi.
- Red Oni, Blue Oni: Contrary to their color-schemes, Gekkamaru is the calmer and more practical blue oni, where Kuroyuki is the cheerful, happy-go-lucky red oni.
- Supreme Chef: He's one of the few shinobi with quite exceptional cooking skills.
- Undying Loyalty: To Enju. Kagari's spell might have something to do with it, but he remains loyal to her even once it's broken.
Gekkamaru's younger brother and Enju's foster brother. Right after he was born, he and Gekkamaru were taken in by her family. Cheerful, carefree and clever, Kuroyuki can also be quite cunning. He was sent away on an extended mission when he was eight, and after 8 years, has finally returned.
- Acquired Poison Immunity: In his route, he casually mentions that he's been trained to take poison.
- Always Second Best: In Hanzo's route, he says he feels this way when it comes to Enju's affections; first to Gekkamaru, later to Hanzo.
- Amnesiac Hero: Kuroyuki's ninjutsu feeds off of memories. By the time of the events of the game, his feelings for Enju and his resentment toward Gekkamaru are all he remembers from his childhood.
- Failed a Spot Check/Nice Job Breaking It, Hero!: On some routes (definitely on his own but also implied on Goemon's and Hanzo's), he is the one who murders Hideyoshi, on orders from Kando Ueno. Apparently he didn't realize that Enju was in the next room, and she ends up getting framed for the crime.
- Dogged Nice Guy: Kuroyuki, in Chojiro and Gekkamaru's routes. Played with in Goemon and Hanzo's. He usually shows up to side with Enju even when he's not being romanced, however, it's implied that he's the actual killer of Hideyoshi in Goemen and Hanzo's routes, making his decision to side with her there perhaps somewhat motivated by guilt.
- Glowing Eyes of Doom: One of Kuroyuki's eyes glows red whenever he uses his shadow techniques.
- Hidden Depths: Kuroyuki's bright disposition is an act he puts on in an effort to recapture his identity that he lost along with his memories.
- If I Can't Have You... : Kuroyuki mentions that he wanted to make a world where only they could live in, even if it means making Enju hate him. Eventually subverted, as he realizes he was wrong to try to keep Enju to himself.
- In Love with Love: Since training for Kagehami (Shadow Eater) required him to stay in the dark for 8 years and have it eat away at his memories and soul, the only way he was able to cope was to summon an illusion of Enju. After they confess, Enju says that maybe he's not really in love with her, but the memory of her.
- I Want My Beloved to Be Happy: After realizing it was wrong and selfish of him to manipulate Enju, he decides instead to try to create a world where she can be happy without him by killing anything that could harm her.
- Loss of Identity: Kuroyuki went through this after his childhood training destroyed all of his memories.
- Love Confession: To Enju. He tells her so much that she thinks he's joking.
- Love Makes You Crazy: After Hideyoshi's murder, he breaks Enju out of jail, tells her no one is on her side except him, her friends are headed to kill her, and the only way to survive is for them to be together forever. He also ties their wrists together after she finds out that he's been lying.
- Morality Chain: Enju becomes this to him, as she's the only memory of his childhood he has left, and one of the few things tethering him to his humanity.
- Never Found the Body: A subversion occurs in Chojiro's route. Kuroyuki's body presumably gets washed away in a river during a fight, and Chojiro and Enju presume that he is dead. In the bad ending, he's never seen again, but in the good ending, he resurfaces to assist in their escape.
- Not Blood Siblings: Kuroyuki was adopted into the Koga family and was raised alongside Enju until he was 8.
- The One That Got Away: With Enju. Regrets being sent away for 8 years and being apart from her, so he wants to make as many memories with her as possible.
- Please Don't Leave Me: Says this repeatedly as he's sucking the poison out of Enju.
- Red Oni, Blue Oni: Contrary to their color-schemes, Gekkamaru is the calmer and more practical blue oni, where Kuroyuki is the cheerful, happy-go-lucky red oni. At least, on the surface he is.
- Shadow Pin: One of Kuroyuki's techniques.
- Shell-Shocked Veteran: He was subjected to years of mental torture during his training, and the jutsu he learned there specifically feeds on memories and souls, rendering him a shell of his former self. Part of the reason he fixates on Enju is because she is the only person he remembered after forgetting the rest of his childhood, and the only person who has kept him from losing his mind already.
- Sibling Rivalry: Mostly one-sided from him to Gekkamaru, as he somewhat resents Gekkamaru for being chosen as Enju's protector over himself.
- Sinister Scythe: He uses two kusarigama.
- Stepford Smiler: Kuroyuki puts on a cheerful front, but his route reveals that he is nowhere near as composed as he seems. Years of torture and learning techniques that feed on your soul will do that.
- Yandere: Somewhat justified and downplayed, given his backstory. His route reveals that he'd been tortured for the 8 years he was away from Koga and that his memories of his childhood are all but gone aside from Enju. He becomes obsessed with her because he views her as his only connection to humanity and the only thing keeping him from being a complete "monster". When he realizes she'd been blamed for Hideoyoshi's murder, hatches a plan to rescue her without their friends and convinces her not to trust anyone but him. He mercilessly kills almost all the shinobi that come for Enju, though he doesn't do anything worse than beating up her friends (and Goemon) when they come. After his deception is revealed to Enju, he decides instead that he wants to create a happy world for her, and puts all his energy into removing all threats to her life before he's executed for Hideoyoshi's murder..
- You Are Worth Hell: After Enju is claimed to be Hideyoshi's murderer, Kuroyuki doesn't care if he has to kill to stay with her.
The son of the late leader of Iga, Tanba Momochi, Enju's cousin. After losing his family and clan in the Tenshou Iga War at the age of five, he joined Kōga with his surviving people. Since he is the son of the Head Shinobi of the fallen Iga, he's naturally observant and calm. His skills as a shinobi are eminent in Kōga, as he's also a teacher for Enju and the others.
- Aloof Big Brother: He's the strong, stoic, older brother figure to Enju and her friends in Koga.
- Big Brother Mentor: He taught the other younger shinobi how to fight.
- Conflicting Loyalty: In his route, Chōjirō hesitates to side with Enju due to the fact that Kōga will be destroyed if they do not kill her, and for Chōjirō, who has already lost his home once before, the thought of losing his home again frightens him.
- Character Tics: He clenches his fists when he's emotionally distressed.
- Dandere: He's generally quiet and emotionless, but opens up to Enju by the end of his route.
- Intimate Healing: In his route, he is poisoned by the Nokizaru shinobi and loses consciousness, forcing Enju to give him the antidote mouth-to-mouth. He teases her about this later after Hanzo points it out to him.
- Kissing Cousins: Enju's mother was the younger sister of Chōjirō's father, making Enju and Chōjirō cousins.
- Long-Haired Pretty Boy: He has long hair and is quite handsome.
- The Quiet One: He doesn't speak much and is largely introspective.
- Mutual Kill: In his bad ending, he and Enju decide to kill each other rather than truly fight to the death for Hideyoshi's amusement.
Known as the right-hand-man to Ieyasu Tokugawa and the leader of the Tokugawa shinobi, Hanzō is one of the few surviving members of the now-destroyed Iga clan. Calm, blunt and efficient, he has made a name for himself as the greatest shinobi in Japan and is looked at with great admiration by Enju and her peers.
- Adorkable: He gets pretty embarrassed when Ieyasu shows Enju how beautiful his handwriting is.
- Brutal Honesty: He does not hold any punches when pointing out one's flaws as a shinobi, but also doesn't pass any judgement about said flaws.
- The Champion: To Ieyasu. He's Ieyasu's right-hand-man and most trusted accomplice, more than willing to put his life on the line to protect him.
- Childhood Friends: He was friends with Enju's mother Kagari since they came from the same village and were close in age.
- Commonality Connection: With Enju through her mother.
- Conflicting Loyalty: At the end of his route Ieyasu orders him to kill Enju to secure him the position of Hideyori's guardian. Having fallen in love with Enju at that point, Hanzō feels extremely conflicted about fulfilling his mission and ultimately chooses to protect her from the rest of his clan. Fortunately, Ieyasu lets him off the hook by only ordering proof of Enju's death (in the form of her bloody sash) instead of her body, allowing her to live on in secret and sparing Hanzō from defying his orders.
- Curb-Stomp Battle: Hanzo is considered World's Best Warrior in-universe and he lives up to the title. Any enemy he goes up against tends to fall pretty quickly, and he only really has trouble in the latter chapters of his route because he's fighting Enju's friends and wants avoid killing them for her sake. The only real exception to this is Goemon, who seemed to be able to stand against him better than most the one time they fought in earnest.
- Death Glare: Has an unfortunate habit of looking very serious and sharp when he doesn't necessarily mean to be, and this combined with his stoicism means that he comes off as very intimidating to younger shinobi like Enju and her friends. Even the normally unruffled Kuroyuki is nervous in his presence.
- Dual Wielding: He wields two large daggers.
- Hidden Depths: He has calligraphy-level handwriting and knows a lot about tea ceremony, quite contrary to his reputation as a terrifyingly skilled shinobi.
- Historical Domain Character: Hanzō Hattori was a real historical figure who was loyal to Ieyasu Tokugawa, however he was a warrior rather than a shinobi, and probably less of a Hunk than his Romance Game counterpart.
- My Greatest Failure: Enju's mother, Kagari, spoke to him while she was pregnant and asked him to run away with her; he wasn't able to, and she ended up being murdered by Kando. Hanzo is deeply remorseful, feeling that she and Enju would have lived much happier lives if he'd done as she asked.
- The Stoic: He's generally quiet and keeps his emotions to himself.
- Undying Loyalty: When he fails his mission because he'd fallen in love with Enju and thus refused to kill her once Ieyasu ordered him to, he wants to commit suicide rather than live as a nukenin.
- What Is This Feeling?: Downplayed in his route. Hanzo is bewildered by his feelings for Enju at first because he's never loved anyone romantically before, but he figures it out pretty quickly and isn't shy about expressing it afterwards.
An elusive and infamous thief with the peculiar habit of leaving a warning note in the homes he will rob, listing the exact item he intends to steal. Though charming and laid-back, Goemon is considered highly dangerous by the state for his incredible skill and anonymity. A team of Kōga shinobi, consisting of Enju and her friends, is hired to sleuth out information aiding in his capture.
- Break His Heart to Save Him: He pretends to betray Enju near the end of his route in order to trick the Fuma Clan into helping him stage her Fake Death in front of the elders so they will stop hunting her. He later apologizes to her for it, saying he'd wanted to let her in on his plan, but couldn't do to the Fuma watching him so closely.
- The Charmer: He's very slick and charming, openly flirting with Enju even minutes after meeting her.
- Chivalrous Pervert: He's generally polite and kind, but openly admits to "having fun" with women.
- Friend to All Children: His route reveals that he is actually quite good with children.
- Handsome Lech: Good-looking and quick to rattle off compliments to any lady who will hear them.
- Hidden in Plain Sight: Goemon attempts this while the Kyo shinobi are hunting him, standing around unobtrusively and smoking a pipe to cover up the lingering smell of smoke bombs. Unfortunately for him, Enju can differentiate between the two smells and can also smell the blood on him.
- Historical Domain Character: Goemon Ishikawa was a real historical figure and thief who targeted the wealthy during the reign of Hideyoshi Totoyumi, however he was not a shinobi and probably not a Bishōnen.
- Internal Reveal: The fact that he and the strange man named "Goro" Enju meets are one in the same is treated as a plot twist, but one look at the game's relationship menu will spoil it long before its acknowledged in the plot.
- Just Like Robin Hood: Except he is based on a real person.
- Loveable Rogue: He's a thief, but he exclusively targets the rich and is actually quite popular among the common folk for it.
- Nice Guy: He doesn't have any particular reason to protect Enju, he simply decides to because he likes her and does so even in some of the routes where he's not being romanced.
- Thou Shall Not Kill: He has a strict personal rule against killing, and will avoid doing so whenever possible. This is only subverted in his bad ending, in which he snaps after witnessing Enju's death and uses a ninjutsu to make the elders murder each other.
- Tranquil Fury: His bad ending. After Enju dies, he very calmly announces to the room that they're all going to die for what they've done to Enju. Hanzo is quick enough to grab Ieyasu and escape, but no one else is that lucky.
- Yandere: His bad ending dips its toe into this. After Enju is killed by Yodo, he uses a powerful ninjustsu to create illusions that cause the Elders (aside from Ieyasu, who Hanzo manages to get out of the room just in time) to start murdering each other. The CG plays heavily on Yandere imagery as he stares straight ahead with blank, teary eyes, cradling Enju's body as the carnage rages on around them.
Enju's father and leader of the Koga clan.
- Abusive Parent: He's emotionally distant and neglectful to Enju even early in the game, but becomes outright malicious to her later when he allows her to be used as a scapegoat for the murder ordered, or the trophy for Hideoyoshi's game to choose his son's guardian. In more than one route, he raises a weapon against his own daughter, and in Kuroyuki's bad ending he actually kills her.
- Asshole Victim: In the routes where he dies, you will probably have a hard time managing to feel any sympathy for him, especially since you've probably just learned about something horrible he did.
- Devil in Plain Sight: Given his Villainous Fashion Sense and the perpetual evil grimace his sprite wears, it comes as no surprise that Enju's father is evil.
One of Enju's childhood friends who is a ninja of Koga.
- Belligerent Sexual Tension: With Kyara. They constantly bicker, and though it's never outright confirmed, one of the common route bonus scenarios as well as main-game subtext suggests they have more than platonic feelings for each other.
- Self-Duplication: His main ninjutsu is the ability to make illusionary copies of himself.
- Super Speed: He is one of the fastest Koga shinobi and he uses speed to his advantage in battle.
- Wolverine Claws: He uses tekagi-shuko (hand claws).
Another one of Enju's friends, also a ninja of Koga.
- Belligerent Sexual Tension: With Ennosuke. They constantly bicker, and though it's never outright confirmed, one of the common route bonus scenarios as well as main-game subtext suggests they have more than platonic feelings for each other.
- Dead All Along: In Gekkamaru's route. After she works with Enju to stop some of the shinobi who had been controlling her body via ninjutsu, its revealed she'd been dead all along and that the ninjutsu was the only thing keeping her alive.
- Epic Flail: She uses a chigiriki, a Japanese flail weapon.
- Fiery Redhead: Kyara is as fiery as her red hair suggests.
- Red Oni, Blue Oni: With Enju. Kyara is the more fiery red oni to Enju's shy and sweet blue oni. Their colour schemes even line up perfectly.
- Tomboyish Ponytail
- Tomboy with a Girly Streak: She wears pants in her civilian outfit and shinobi gear and both have elements of flowers and fuchsia.
- Tsundere: Mostly with Ennosuke, whom she snipes with at every opportunity. However, she and him are heavily implied to have feelings for each other, and Enju notes that they know one another so well that they fight seamlessly as a team. She is devastated by his death in Chojiro's route, though it's not too long afterward that she also dies.
Another one of Enju's friends and the youngest of them.
- The Baby of the Bunch: She is the youngest of the friend group.
- Deadly Disc: She uses two chakram as a weapon.
- Supreme Chef: While her shinobi skills aren't great, she is good at cooking and sewing.
- Third-Person Person: It's not translated in the English written dialogue, but listening closely to Kasumi's recorded dialogue reveals her to be one of these.
An Influential Daimyo who rules the Kanto Region and one of the Five Elders. He owns his own shinobi clan which is currently lead by Hanzō Hattori.
- The Gadfly: According to Hanzo, Ieyasu enjoys teasing him for the sake of his own amusement.
- Guile Hero: Straddles the line between this and Magnificent Bastard in most routes, as he's more an Anti-Hero and often takes a True Neutral position in contrast to the full antagonism of the other Elders. He tends to be somewhat conniving and is planning to take over the country soon after the events of the game, according to Hanzo (and actual Japanese history). That said, he doesn't particularly want Enju to die and even sends Hanzo to protect her in most routes despite that he is the World's Best Warrior and could probably kill her easily.
- He is this more straight-forwardly in Hanzo's route. He agrees to simply use proof of Enju's death (in the form of her bloody sash) to ensure he becomes Hideyori's guardian instead of insisting on her body, allowing Enju to live on in secret and sparing Hanzo from having to either kill her or defy his orders.
- Historical Domain Character: Ieyasu Tokugawa was a real historical figure who did actually take over Japan after Hideyoshi's death, being the forefather of the Tokugawa Shogunate which lead Japan for over 250 years between the 17th and 19th centuries. He was quite a bit more ruthless than his in-game counterpart though, and probably wasn't a ridiculously pretty Bishōnen.
- Long-Haired Pretty Boy: He has long hair and is very good-looking.
